Subject: [REGRESSION][v3.4-rc1] PCI: add a PCI resource reallocation config option
Date: Wed, 27 Nov 2013 15:22:43 -0500 [thread overview]
Message-ID: <52965493.8060208@canonical.com> (raw)
Hi Yinghai,
A kernel bug was opened against Ubuntu [0]. After a kernel bisect, it
was found that the following commit introduced the bug:
commit b07f2ebc109b607789f648dedcff4b125f9afec6
Author: Yinghai Lu <yinghai@kernel.org>

PCI: add a PCI resource reallocation config option
The regression was introduced as of v3.4-rc1 and also exists in current
mainline.
The bug seems platform specific since we have not had allot of other
reports. The bug is preventing ixgbe to probe Intel x520 NIC's.
It would be easy enough to disable the PCI_REALLOC_ENABLE_AUTO config
option, but I wanted to get your feedback since you are the author. It
looks like the bug reporter may also be able to work around the problem
with the pci=realloc=.
Thanks,
Joe
